The Science Behind Botox and Dysport: Are They Really Different?

In the world of aesthetic medicine, few terms generate as much interest, and confusion, as Botox and Dysport. These names come up constantly in consultations, social media, and patient recommendations, but are they truly the same? While many people use them interchangeably, the truth is that there are key differences that can impact your treatment results.

In this article from Curage Med, we’ll break down the science behind Botox and Dysport to help you understand their distinctions and make an informed choice for your aesthetic goals.

What Are Botox and Dysport?

Both Botox and Dysport are brand names for botulinum toxin type A, a purified neurotoxin used to temporarily relax the muscles responsible for dynamic wrinkles (those formed by facial expressions). This toxin works by blocking the release of acetylcholine, the neurotransmitter that signals muscle contraction.

Botox is manufactured by Allergan, and Dysport is produced by Ipsen. Both products are approved by international regulatory agencies like the FDA (U.S.) and Cofepris (Mexico) for both aesthetic and therapeutic use.

Composition and Formulation: Not Exactly the Same

Although both products contain botulinum toxin type A as the active ingredient, their formulations differ in key ways:

• Units are not equivalent: 1 unit of Botox is not the same as 1 unit of Dysport. In general, around 2.5 to 3 units of Dysport are needed to match the effect of 1 unit of Botox.
• Molecular weight and accompanying proteins: Botox and Dysport include different complexing proteins, which influence how they spread in tissue and how the body may respond to them over time.
• Diffusion in tissue: Dysport tends to spread more broadly, which can be advantageous for treating larger areas like the forehead, but less ideal when precise application is needed, such as between the brows.

Onset and Duration of Effects

Another key comparison point is how quickly they begin to work and how long their effects last:

• Dysport: tends to show visible results within 2 to 3 days.
• Botox: usually takes a bit longer, with effects appearing between days 3 and 5.

Both treatments generally last around 3 to 4 months, although this can vary based on the patient’s metabolism, the dosage used, and the injection technique.

Diffusion vs. Precision: Which One Suits Each Area?

Dysport’s wider diffusion makes it a good choice for broader areas like the forehead. Botox, on the other hand, is more precise, ideal for smaller, more targeted areas like crow’s feet or frown lines.

The decision may also depend on factors like muscle strength, skin thickness, and the desired aesthetic outcome (softer vs. more defined).

Which One Is Better? It Depends on You

There is no universal answer. Both products are safe and effective when administered by a trained professional. What truly matters is a personalized medical evaluation, because each face has unique needs.

Some patients have even tried both products at different times and preferred one over the other based on how their body responded, how quickly results appeared, or the overall look achieved.
